Description
50 Ohm R-Test AccuStability Cable | TPU/FEP Jacket | LD PTFE Dielectric
The ROSNOL AS26A R-Test AccuStability cable is a high-performance 50 Ohm coaxial solution designed for precision RF and microwave applications up to 26.5 GHz. It features a solid silver-plated copper (SPC) inner conductor, low-density PTFE dielectric, and dual shielding layers of silver-plated copper foil and braid. The cable is triple-jacketed with FEP, TPU, and braided fiber, with an overall diameter of Ø7.30 mm [Ø0.287 in]. Minimum static bend radius is 9.65 mm [0.380 in].Electrical characteristics include 86.0 pF/m capacitance, 80% signal velocity, 4.30 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness reaches ≥ 100 dB up to 18 GHz, with a maximum operating voltage of 1.9 kVrms. Phase stability vs bending is ±3.0° typical / ±6.5° max, and amplitude stability is ±0.02 dB typical / ±0.04 dB max. Attenuation ranges from 0.26 dB/m (0.08 dB/ft) at 1 GHz to 1.47 dB/m (0.45 dB/ft) at 26.5 GHz. Max CW power is 248 W at 10 GHz.
